PIGKER-STICK.

Application filed February 2'7, 1912.

To all whom at may concern Be it known that I, EUGENE CI-IEvnnTrn, a citizen of the United States, residing at Shirley Center, in the county of Middlesex and State of Massachusetts, have invented a new and useful Picker-Stick, of which the following is a specification.

This invention relates to mounting and operating means for picker-sticks, and is an improvement over my Patents Nos. 694,352 patented March 4:, 1902 and 865,680 patented Sept. 10, 1907.

One of the principal objects of the present invention is to provide an improved form of connection for the rocker-piece shown in these patents, whereby the same will operate along the picker-stick throughout the distance from the bottom thereof to the point of application of power, thus distributing the strain and increasing the longevity of the picker-stick as well as of the rocker-piece.

Another object of the invention is to provide an improved bottom connection for the picker-stick and adjustment for the rockerpiece connected therewith.

The invention also involves other features of construction as will appear hereinafter.

Reference is to be had to the accompanying drawings in which Figure 1 is a side view of a picker-stick connected up in accordance with the present invention, Fig. 2 is an end View of the bracket therefor. Fig. 3 is a side view of the bracket; and Fig. 4 is a side View of a modification.

In the present invention the parts are 'mounted on a bracket 10 preferably consisting of a casting secured to the usual pivot member or rock shaft of the lay by a bolt 11 or in any other desired way. On this bracket is an integral projection 12 preferably of cylindrical form designed to be covered by a rubber, metal or other yielding rotary ring 13 for receiving the blows from the picker-stick as will appear hereinafter. At the top of the bracket is a horizontal bearing 14 in which is hung the end of a swinging link or movable member 15 which is provided on its lower end with an integral pivot 17 parallel with the bearing. This pivot 17 is designed to pass through a perforation in the bottom of the pickerstick 20 and form the pivotal support for the bottom thereof. It also forms the sup- Specification of Letters Patent.

port or bearing for a link 21 which is proyided with a longitudinal slot 22. This link is connected through this slot adjustably by a bolt 23 with the rocker-piece 24. This rocker piece is otherwise shown similar to the corresponding element in my above men tioned patents, and it is pivotally connected with the side pieces 25 which are mounted on the sweep arm 26.

The utility of the adjustment of the bolt 23 consists in the fact that by this means the rocker-piece can be connected with the pivot 17 almost directly so that it swings about it and yet adjustment can be secured so as practically to lengthen out the rocker-piece or shorten it, that is, raise it or lower it along the picker-stick. At the same time it can be so arranged by the proper adjustment that it will lie along the picker-stick parallel with its adjacent surface when the power is acting through it to operate the picker-stick. In this way the blows on the picker-stick are distributed over the larger are-a and yet not diminished in force. The rubber ring against which the lower end of the picker-stick operates is used for the purpose of deadening the blow and thus permitting the use of a comparatively small projection at this point without danger of breaking the casting.

It will be seen that the support for the bottom of the picker-stick is movable so as to allow all necessary motion thereof for the purpose of getting etlicient operation.

In the form shown in Fig. 1 an integral metal bumper 32 is shown.

l/Vhile I have illustrated and described a single embodiment of the invention, 1 am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but

What I do claim is 1. In a construction of the class described, the combination with a lay, of a picker stick supported and freely movable outwardly therefrom to swing on a pivot at the bottom, and a rocker piece mounted to swing about the same pivot and extending along and in contact with the picker stick throughout the length of the rocker-piece and arranged to impart an unyielding forward stroke at an intermediate point of the picker stick.

2. In a construction of the class described, the combination with the lay, a member connected therewith and freely movable away from the lay at each beat thereof, said member having a pivot thereon, a picker stick and sweep arm, the picker stick being pivotecl on said pivot, of a rocker piece mounted to swing about said pivot and to extend along the picker stick, and side pieces for connection with the sweep arm pivotally connected with said rocker piece near the upper end thereof.

3. In a construction of the class described. the combination with a picker stick and sweep arm, of a member having a pivot about which the picker-stick is adapted to swing, a link pivoted on said pivot, a rocker piece connected with said link and extending along and arranged to engage the picker stick substantially all the way from the pivot to the sweep arm, means for connecting the rocker-piece with the sweep arm, and means for adjusting the bottom of the rocker piece longitudinally of said link.

t. In a construction of the class described, the combination of a rocking bracket, a link pivoted thereto and provided with a pivot, a picker-stick connected with said pivot, a link pivoted on said pivot and having a longitudinal slot therein, and a rocker piece adjustably connected with said link through said slot for connection with a sweep arm.

5. In a construction of the class described, the combination of a bracket having a horizontal bearing near the top thereof, a member mounted to swing in said bearing and having a pivot at the lower end thereof, a picker-stick mounted to swing on said pivot, a link pivoted on the pivot, and a rocker piece for operating the picker-stick adjustably secured at its lower end to said link.

6. In a construction of the class described. the combination of a cast metal bracket hav ing a fixed cylindrical projection extending therefrom and a bearing at the upper end, a resilient ring around said projection, a link depending from said bearing, and a picker stick pivoted at the bottom to said link independently of the projection and adapted to engage said ring during its operation.

7 In a construction of the class described, the combination of a rocker bracket having an upwardly projecting arm, a link pivoted to said arm and extending downwardly therefrom, and a picker-stick pivoted to and supported by said link and arranged to swing about its pivotal connection therewith.

8. In a construction of the class described, the combination of a rocker bracket, a link pivoted thereto and extending downwardly therefrom, and a picker-stick pivotally sup ported by said link at the lower end thereof and adapted to swing about its pivotal con nection with the link.

9. In a construction of the class described, the combination of a rocker bracket, a link pivoted thereto and extending downwardly therefrom, a picker-stick pivotally supported by said link at the lower end thereof and adapted to swing about its pivotal connection with the link, and a stop for the bracket for receiving the blows from the picker-stick In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
